<h1>No Such Badge 2013</h1>

<p>No Such Badge is the twenty-sixth hardware revision of the
GoodFET, owing its heritage to
 <a href="/hardware/facedancer21/">Facedancer21</a>, of which it is a
clone.  Unlike the general-purpose GoodFET boards, the only purpose
of this board is to allow USB devices to be written in host-side
Python, so that one workstation can fuzz-test the USB device drivers
of another host.  This board replaces the MAX3420E of earlier
Facedancers with a MAX3421E, allowing for optional host mode through a
USB A receptacle.
</p>

<p>The badge is not available for order, but you might be able to get
an extra one from an attendee of the No Such Conference or from that
conference's organizers.  See the <a href="/orders/">Orders</a> page
for details on ordering other Facedancer PCBs.</p>

<h2>CAD Files</h2>

<p>Eagle CAD 6.x files for the design can be found in
/branches/nsb2013 of the GoodFET subversion repository, or as
manufacturable Gerber files as
<a href="/releases/nsb2013.zip">nsb2013.zip</a>.</p>

<h2>Bill of Materials</h2>

<p>The MSP430F2618TPM may be replaced with a 2617, 2619, 2417, 2418,
or 2419 chip, provided that the $mcu variable is set.</p>

<p>Resistor values can be approximated, and the 1.0&mu;F capacitors
are probably unneeded.  Be sure to get the 64 pin variant of the
MSP430F2618, as 80-pin versions are also manufactured.

<p>* These should match the required capacitance of the crystal.  18pF is wrong, but close enough to work.</p>
<p>** The /US SMD package works as an alternative.</p>

<p>If you need help selecting parts, you can follow
this <a href="http://www.reddit.com/r/netsec/comments/10g7f0/goodfetfacedancer_parts_list/">example
Digi-Key order</a>, but be sure to replace the MAX3420 with a MAX3421.
You will also need the USB Type A receptacle for Host Mode.</p>


<h2>Construction</h2>

<p>Place the components as shown in the comments of this Flickr image.
As this is a surface-mount design, be sure that you are familiar with
such techniques or have assistance before beginning assembly.  See the
errata section for details on where to run fly-wires, as two pins
were not connected in the PCB layout.</p>

Tutorial</a> for more detailed explanations.</p>

<h2>Usage</h2>

<p>Build and flash firmware with the following commands.  This board
self-flashes over USB through a masked-ROM bootloader, so there is no
need for an external programmer.</p>

<p><pre>export board=nsb2013
make clean install
goodfet.maxusbhid
</pre></p>

<h2>Errata</h2>

<p>None, we hope!</p>
